Absolute dose calibration is important for process simulation and transfer of manufacturing to different production line or locations, but until recently, no viable standards were available. With the creation of a NIST standard for boron, it is now possible to determine the absolute dose of a boron implant with a relative uncertainty of less of 5%. The does of boron ion implants were measured by secondary ion mass spectrometry at two different laboratories using similar analysis protocols. The disagreement between the labs was typically less than 2%. The contributions from both B-10 and B-11 were found to be significant.
